Rosettes of asci from crosses between Neurospora metzenbergii 8881 and (a) the Sk‐2 backcross strains or (b) the Sk‐3 backcross strain. For crosses to Sk‐2, nearly all asci are aborted without producing spores of any kind, but occasionally will produce an ascus with small aborted spores (*). For Sk‐3 crosses, asci contain only small aborted spores most of the time, but occasionally viable spores are found (*).
